text: I'll assume you're just using JMeter as a type of Web Crawler with a fixed set of pages to consume, and you're only measuring response times and http status.
  
  
  Create a thread group of 100 users
  Place a CSV Data Set Config under the thread group
  
  
  The CSV contains one URL per line
  The CSV loads into a parameter named "URL"
  
  A HTTP Sampler is used where the hostname is set to ${URL}
  
  
  Specify any assertions you need, eg "200" http response
  
  Run it and see how it goes
  
  
  Heres some pictures of the setup in JMeter using the default samplers and config elements;
  
  
  Create the threadgroup:
  Create the CSV Reader
  
  Create the HTTP Sampler
  
  Have an assertion checking you get a decent response
  
  Optionally record the responses for review
  
  
  The CSV File i'm using looks like:
